Yesterday’s WWDC 2012 keynote saw Apple unveil a whole slew of new products. Items on yesterday’s agenda included OS X Mountain Lion, iOS 6, new updates to the MacBook Air, and the existing MacBook Pros, and a brand new MacBook Pro with a retina display.

One of the more interesting parts of the announcement regarding the new MacBook models was the fact that they were ready to ship from the online Apple Store yesterday. There was no pre-order period. As soon as the Apple Store came back online, you could order all five models (plus the new Mac Pro).

Scarcely had the dust settled from the announcement, though, than the new MacBook Pros – including the retina display model – were getting their very first software update. Just a few hours after the keynote ended, Apple released a 1.06GB software update aimed squarely at the brand new MacBook Pros. There’s not a lot of detail about what the new update does. All Apple’s support page says is that it improves graphics stability, external display support, and USB 3 device support.

Unsurprisingly, there aren’t any sales figures available yet from Apple on how well the new retina display MacBook Pro (or it’s less flashy cousins) sold following yesterday’s announcement. At nearly $2200 a pop, we shouldn’t expect iPhone or iPad levels of sales for the next gen MacBook Pro, though it’s bound to be pretty popular, even so.
